The MCU_M4FSS supports a 48-bit input interface for synchronizing to the global time counter (GTC). The 48-bit timestamp can be appended with ITM messages. Timestamping is a mechanism whereby a global timestamp value is periodically inserted at strategic locations into the trace stream. Timestamps can be used to correlate trace from various sources. Each trace source samples the timestamp value and inserts it as an absolute value into the trace stream.
The global timestamp value coming to the MCU_M4FSS is gray-encoded. It is then internally converted to its binary value.
